The goal of viscosupplementation is to replenish synovial fluid, which will improve patient symptoms and mobility. Viscosupplementation of the knee with hyaluronic acid injections has been shown to improve symptoms in patients with osteoarthritis. Recent studies have shown that this improvement may be highly variable based on the time from treatment, especially in the first 12 weeks following treatment. The purpose of this study is to document the outcomes following a treatment protocol in which corticosteroid is used in addition to the initial Synvisc injection in the series of three injections.
